On Thursday 13 April 2017, Arctia’s icebreaker Sisu returned to Katajanokka, Helsinki, after icebreaking duty in the Bothnian Bay. The Sisu departed to assist other vessels on 31 January. During this period, it assisted 203 vessels and towed 53.
“Although the ice extent has not been that large this season, ice cover ijn the Bothnian Bay has stayed in one place exceptionally long. This is due to prevailing winds. We have witnessed hard ice pressure in the ice field from time to time during the whole season”, explains Matti Björkman, Master of IB Sisu.
